The configuration settings on the BB-400 are stored as a YAML file in the /boot partition of the device. The BB-CLI reads and writes to this file. Below is a brief guide on each section of the configuration file.

version:

The version section has information regarding the product number, the hardware revision code and the version of software currently installed on the device. These settings cannot be set.

io:

This section contains settings relating to the DIO lines and the protocol settings used by the BB-IO-Server.

fw_version:

This represents the Arduino DIO firmware version number. To install a new firmware version on the Arduino, input the new firmware file location as an argument.

global:

This is the DIO lines configuration settings that apply to all the 8 DIO lines.

Setting name Description Possible values
counter_update_direction This is when the counter needs to be updated on either
the falling edge or rising edge of the input signal
falling_edge
rising_edge
counter_mode This is the size of the register to store the count value
16 bit = 0 -> 65,536 , 32 bit = 0 -> 4,294,967,296
16_bit_counter
32_bit_counter

lines:

This contains the settings that can be set individually on each DIO line.

Setting name Description Possible values
label User defined label for the DIO line Any string containing alphabets,
numbers, spaces, underscore and hyphen.
mode Whether the line is an input or output or not used input
output
not_set
unused

protocols:

This section contains the settings for the different protocols

ascii_tcp:

Contains the port number and the enabled status.

modbus_tcp:

Modbus TCP server conforms to the Modbus TCP protocol as included on Brainboxes' digital IO modules ED-588 or ED-008. Not implemented for this release.

ws_server:

Contains the port number and enabled status.

virtual_serial_port:

The DIO on the BB-400 can be accessed through the virtual serial port to send and receive ASCII commands. The path to the virtual serial port and the enabled state is stored here.

polling_interval:

Describes how frequently the DIO needs to be polled to get the Digital IO lines states (in seconds).

rest:

REST server allows GET and POST requests to view and modify IO state. This section contains the port number and the enabled status.

Protocol Setting name Description Possible values
ascii_tcp enabled Whether the protocol is enabled or disabled true

modbus_tcp port Port number the protocol can access Any number between 0 - 65535
modbus_tcp respond_to_slave_ids Slave ids the modbus master should respond to range or number between 0 and 255
modbus_tcp maximum_connections Maximum allowed connections at a given time Number between 0 and 255
modbus_tcp accept_all_addresses -

ws_server port Port number the protocol can access Any number between 0 - 65535
virtual_serial_port enabled Whether the virtual serial port is enabled or disabled true
false
virtual_serial_port path Symlink to the virtual serial port which
can be used to access the Arduino through the BB-IO-Server
Any valid path

network:

This section contains settings related to ethernet interfaces, wifi and UPnP (Universal Plug and Play).

eth0 and eth1:

This is one of the 2 ethernet interfaces on the BB-400.

eth0 corresponds to the UPLINK port on the front of the case.

eth1 corresponds to the LAN port of the front of the case.

interface and connection settings are common to eth0 and eth1.

interface:

Setting name Description Possible values
mac MAC address Stores the MAC address of the eth0 interface
status Status of the interface active
inactive

connection:

Setting name Description Possible values
name Name of the connection Any string with alphabets,
numbers, spaces, underscore and hyphen.
type IP address assignment type dhcp
static
ip IP address of the connection Can be set only when type is static
gateway IP address of the gateway Can be set only when type is static

radio:

This section has settings related to the wireless connections.

wlan0

Maintains a list of saved connections and status of wlan0. Status can be active or inactive.

wifiap

This section deals with the BB-400 access point mode settings. The SSID name, password and status are the settings stored here. Status can be active or inactive.

bluetooth

The status of the bluetooth is stored in this section. Status can be active or inactive.

upnp:

These values are used by the UPnP server. The UPnP server enables you to find the BB-400 device on the network.

Setting name Description Possible values
enabled Whether the server is enabled or disabled true
false
port Port number the server runs on Any number between 0 - 65535

serial:

Contains all settings related to the serial port on the BB-400. This port is available on the device as /dev/ttySC0

Setting name Description Possible values
enabled Whether the serial port is enabled or disabled true
false
type Serial port protocol - RS232, RS422 or RS485 rs232
rs422
rs485

The other settings are not yet implemented.

docker:

This setting is used to add/ move Docker containers from the system.

Setting name Description Possible values
enabled Whether docker is enabled or disabled true
false
containers List of docker containers that are installed. Each list should contain the properties
image, name, config and running status

system

All settings related to the Linux system are stored here.

rtc

Stores the last date/time the Real Time Clock (RTC) was set.

hostname

Stores the host name of the device

username

Stores the username that set up the device.

password

Stores the password of the user in the username property Passwords are never stored in the config file, instead '****' is used as a placeholder to show that this property is set.
